Mitsubishi Outlander XL. Manual — part 729

CIRCUIT OPERATION
The ETACS-ECU operates the liftgate according to
signal from the liftgate lock release handle.

TECHNICAL DESCRIPTION (COMMENT)
If the signal is not normal, the liftgate will not work
normally. If the signal is not normal, the liftgate lock
release handle or the ETACS-ECU may be defective.

TROUBLESHOOTING HINTS

｠

The liftgate lock release handle may be defective

｠

The wiring harness or connectors may have loose,
corroded, or damaged terminals, or terminals
pushed back in the connector

｠

The ETACS-ECU may be defective

DIAGNOSTIC PROCEDURE

Required Special Tools:

｠

MB991223: Harness Set

｠

MB992006: Extra Fine Probe

｠

MB991958: Scan Tool (M.U.T.-III Sub Assembly)

｠

MB991824: Vehicles Communication Interface (V.C.I.)

｠

MB991827: M.U.T.-III USB Cable

｠

MB991910: M.U.T.-III Main Harness A

STEP 1. Check liftgate lock release handle connector F-09
for loose, corroded or damaged terminals, or terminals
pushed back in the connector.

Q:Is liftgate lock release handle connector F-09 in good

condition?

YES:

Go to Step 2.

NO:

Repair or replace the damaged component(s). Refer to

GROUP 00E, Harness Connector Inspection P.00E-2. Repair
the liftgate lock release handle. If the liftgate lock
release handle operates normally, a correct signal is
sent from the liftgate lock release handle.

STEP 2. Check the liftgate lock release handle.
Remove the liftgate lock release handle. Refer to GROUP 42Ac,
Liftgate Handle and Latch P.42Ac-10. Then check continuity
between the switch terminals.

Q:Is the liftgate lock release handle in good condition?

YES:

Go to Step 3.

NO:

Repair the liftgate lock release handle. If the

liftgate lock release handle operates normally, a correct
signal is sent from the liftgate lock release handle.

STEP 3. Check the ground circuit to the liftgate lock release
handle. Measure the resistance at liftgate lock release
handle connector F-09.

(1)

Disconnect liftgate lock release handle connector F-09 and
measure the resistance on the wiring harness side of the
connector.

Connector F-09
(harness side)

(2)

Measure the resistance value between terminal 2 and
ground.

｠

The resistance should be 2 ohms or less.

Q:Is the measured resistance 2 ohms or less?

YES:

Go to Step 5.

NO:

Go to Step 4.

STEP 4. Check the wiring harness between liftgate lock
release handle connector F-09 (terminal 2) and ground.

Q:Is the wiring harness between liftgate lock release handle

connector F-09 (terminal 2) and ground in good

condition?

YES:

No action is necessary and testing is complete.

NO:

The wiring harness may be damaged or the connector

(s) may have loose, corroded or damaged terminals, or
terminals pushed back in the connector. Repair the wiring
harness as necessary. If the liftgate lock release handle
operates normally, a correct signal is sent from the
liftgate lock release handle.

STEP 5. Check ETACS-ECU connector C-313 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.

Q:Is ETACS-ECU connector C-313 in good condition?

YES:

Go to Step 6.

NO:

Repair or replace the damaged component(s). Refer to

GROUP 00E, Harness Connector Inspection P.00E-2. If the
liftgate lock release handle operates normally, a correct
signal is sent from the liftgate lock release handle.

STEP 6. Check the wiring harness between liftgate lock
release handle connector F-09 (terminal 1) and ETACS-ECU
connector C-313 (terminal 14).

NOTE:

Also check intermediate connector D-12 for loose,

corroded, or damaged terminals, or terminals pushed back in
the connector. If intermediate connector D-12 is damaged,
repair or replace the damaged component(s) as described in
GROUP 00E, Harness Connector Inspection P.00E-2.

Q:Is the wiring harness between liftgate lock release handle

connector F-09 (terminal 1) and ETACS-ECU connector

C-313 (terminal 14) in good condition?

YES:

Go to Step 7.

NO:

The wiring harness may be damaged or the connector

(s) may have loose, corroded or damaged terminals, or
terminals pushed back in the connector. Repair the wiring
harness as necessary. If the liftgate lock release handle
operates normally, a correct signal is sent from the
liftgate lock release handle.
